OMG! Sorry for being so quiet - I didn't realise this thread was still alive!
Bassspine - Thanks for the heads-up re the B17 down Topsham Road way. I'm aware of some less than reliable folk in that neighbourhood (not all, I hasten to add). I'll be out on a scouting mission soon. In the meantime I've been busy spending a fortune upgrading the security in the shed (including shed-shackle etc!) and around the home in case the little feckers ever try again
I may have discovered at least one of the reasons why this is such a big problem in Exeter. In my recent experience the Police really don't give a $hit. I've not had any contact from them at all, they've not been to survey the scene or take evidence or statements and, in spite of getting the local Councilor involved, they've practically closed the investigation without ever starting it. Exeter is supposed to be a city that actively encourages cycling, but obviously the Police haven't got that message yet and instead treat bike theft as a joke. I've written to the local MP to see if we can get the political view of why this should be the case, so if anyone's interested I'll post the reply if/when I get it?
Thanks again to everyone for the support.
